Allow serving static file outside golte namespaced folder

[winston0410]

In the embedded go file, it only server files under the assets dir:

golte/golte.go

Line 38 in 428bdde

if strings.HasPrefix(r.URL.Path, "/"+renderer.Assets()+"/") {

But as this module is embedding the whole output of Vite, and as that building processing is controlled by golte cli, it would be very useful and easy to serve all files under client.

Usecase:

1. I am using vite-plugin-pwa, and generated some assets. However they are not served, as they are not in golte's assets dir.
2. I tried to pass images to vite's public dir. Those files are copied into the file output, but since golte only serve files under golte's assets dir, they are not served.

Can we remove that condition? @nichady
